The Mantis Fangire (マンティスファンガイア, Mantisu Fangaia), whose true name was The Deads' Miscalculation equals The 4:36 Lie (亡者の誤算=4時36分の嘘, Mōja no Gosan wa Yoji Sanjūroppun no Uso), was a member of the Insect Class.


He carried a scythe and a casket that held the remains of Fangire, which he resurrected as mindless slaves to with the intent of killing Maya for her transgressions against Fangire law. After Kiva destroyed his army, the Mantis Fanigire attempted to revive more Fangire, only to be impaled by the Zanvat Sword as it pierced the casket.
